Barack Obama, the US president, is attempting to seal an Arab-Israeli peace deal that has eluded the region for more than six decades.

Ahead of an initiative expected to be announced in September, Al Jazeera is examining the prospects for peace in a week-long series from Israel, the West Bank, Gaza and Jordan.

One of the issues in the quest is the use of security forces in the Palestinian territories and the guidelines that they operate under.

In the final part of the Planning for Peace series, Al Jazeera's Nour Odeh reports on whether Palestinian security forces can provide security in the West Bank under the "road map to peace" and protect Israel from armed groups.

Al Jazeera's Sami Zeidan questioned Mouin Rabbani, a senior fellow at the Institute of Palestinian Studies and contributing editor to Middle East Report, a quarterly journal, on the conflicting commitments of Palestinian security.
